[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-1476) Table.qualify does not handle dialect diferences

Justin Kolb commented on HHH-1476:
----------------------------------

Please close this issue.

Having to specify the user (catalog.user.table) instead of the shortened form of catalog..table is a work around for this issue. I was first opposed to this, but after thinking about it some more this is not an undue burden on a programmer to have to do this.

> The fix for HHH-699 caused me to discover that Hibernate isn't handling qualifying table names properly. It can be inferred from HHH-699 that not all databases are similar in this respect so I think this should be added to the dialect handling. From my short research I have the following 3 cases:
> SQL Server: database.owner.table
> MySQL: database.table (no schemas it seems)
> Most others: catalog.schema.table
> SQL Server also allows for "database..table" since it does not have schemas but does allow you to write queries that cross databases similar to how you can cross schemas in other database servers.
> Testing on Postgres though I determined that it does not allow "catalog..table" and will only accept "catalog.schema.table", so it dos not match up with SQL Server in this respect. If you write "catalog.table" it thinks you are trying to use a schema so it does not match up with MySQL in this respect.
> So right now only MySQL and SQL Server are the non standard compliant databases. Before 3.1 beta 1, SQL Server was handled correctly; then after that only MySQL was handled correctly.
> I'm not sure how much work it would take to make this change.
